Profile
A computer science researcher and product owner who works on systems that have to scale.
I'm a Product Owner at p36 and a Research Associate and PhD student in the Scalable Software Systems group at TU Berlin, based in Berlin, Germany.
My research sits across distributed systems, software engineering, and benchmarking, and now clinical decision support through the TRANSFER project at TU Berlin. I like systems that have to hold up as they grow, which is usually where the harder problems are.
Lately I've been focused on AI safety in regulated settings: how to build the evidence that lets a team use AI and still answer for it. I care most about the cases where getting the systems right changes outcomes for real people.
